A novel thermoeconomic analysis under dynamic operating conditions for space heating and cooling systems

2019

Abstract Thermoeconomic analysis allows for a deep understanding of the cost formation process within an energy system, providing insights into the possible routes for improvement. Several thermoeconomic approaches are well-established for application in systems with steady operating conditions, such as power plants, while a limited number of applications to air-conditioning systems in buildings have been proposed, due to the difficulties in dealing with very irregular load profiles and unsteady plant operating conditions. This study investigates the potential of Thermoeconomics as a support for decision making in building energy systems, proving its capability to identify trade-offs betwee…

Microtomographic Quantification of Hydraulic Clay Mineral Displacement Effects During a CO2 Sequestration Experiment with Saline Aquifer Sandstone

2013

We combined a noninvasive tomographic imaging technique with an invasive open-system core-flooding experiment and compared the results of the pre- and postflooded states of an experimental sandstone core sample from an ongoing field trial for carbon dioxide geosequestration. For the experiment, a rock core sample of 80 mL volume was taken from the 629 m Stuttgart Formation storage domain of a saline sandstone aquifer at the CCS research pilot plant Ketzin, Germany. Supercritical carbon dioxide and synthetical brine were injected under in situ reservoir p/T-conditions at an average flow rate of 0.1 mL/min for 256 h. X-ray computed microtomographic imaging was carried out before and after the…

Experimental investigation on the compressive behavior of short-term preloaded carbon fiber reinforced polymer-confined concrete columns

2017

Strengthening of concrete columns with fiber reinforced polymer sheets provides a good improvement to the existing structural members in terms of load and strain capacity due to the properties of the composite jacket. A proper knowledge of the load–strain response of the composite members is necessary to design retrofitting intervention of existing structures; however, so far the available design methods do not allow to take into account the effect of the possible presence of service loads on the compressive behavior of the reinforced columns. An experimental investigation on the compressive behavior of preloaded circular concrete columns reinforced with carbon fiber reinforced polymer was …

Measuring the CO2 shadow price for wastewater treatment: A directional distance function approach

2015

Abstract The estimation of the value of carbon emissions has become a major research and policy topic since the establishment of the Kyoto Protocol. The shadow price of CO2 provides information about the marginal abatement cost of this pollutant. It is an essential element in guiding environmental policy issues, since the CO2 shadow price can be used when fixing carbon tax rates, in environmental cost-benefit analysis and in ascertaining an initial market price for a trading system. The water industry could play an important role in the reduction of greenhouse gas (GHG) emissions. This paper estimates the shadow price of CO2 for a sample of wastewater treatment plants (WWTPs), using a param…

Visegrad Euroscepticism: Discursive Nodal Points in Eurosceptic Discourses Surrounding External Actions of the European Union

2018

Increasing support for Eurosceptic parties and movements can be observed in the European Union’s (EU) member states since 2009, when the economic crisis heavily affected the continent. This process has happened also within Central and Eastern European countries, especially in Poland, the Czech Republic, Slovakia and Hungary (collectively referred to as the Visegrad Group countries, or V4 for short). The goal of this paper is an analysis of far-right Eurosceptic politicians and their attitudes towards EU external actions. Using the Thomas Diez concept of discursive nodal points (DNPs) and examining European Parliament (EP) debates, literature about V4 Euroscepticism and media reports, this p…

Going beyond histology. Synchrotron micro-computed tomography as a methodology for biological tissue characterization: from tissue morphology to indi…

2009

Current light microscopic methods such as serial sectioning, confocal microscopy or multiphoton microscopy are severely limited in their ability to analyse rather opaque biological structures in three dimensions, while electron optical methods offer either a good three-dimensional topographic visualization (scanning electron microscopy) or high-resolution imaging of very thin samples (transmission electron microscopy). However, sample preparation commonly results in a significant alteration and the destruction of the three-dimensional integrity of the specimen. Depending on the selected photon energy, the interaction between X-rays and biological matter provides semi-transparency of the spe…

Remembering a past princess : Catherine Jagiellon and the construction of national narratives in Sweden and Finland

2019

This chapter tackles the role a Jagiellonian princess, Catherine Jagiellon, has been given in Swedish and Finnish history culture. It illustrates how her figure has entered the historical-cultural memory of both countries, forging and re-forging their national self-image from the end of the sixteenth century through the Cold War, and into contemporary school history teaching. The chapter highlights the differences as well as the similarities of collective memory and history culture associated with Catherine Jagiellon in two Nordic countries with a shared history. It focuses on largely on physical sites of memory such as archives, museums, cathedrals, chapels, castles, commemorative monument…

Investigation of characterizing methods for the microstructure of cement

2002

Volumetric, gravimetric, calorimetric, flow methods, mercury porosimetry and laser granulometry were used to investigate the surface structure and the sorption behavior of industrial cements and hydrated cement paste. The suitability of the measuring methods is assessed.
